[Playerstage-developers] Driver::GetCommand and Driver::CleanCommand

[Yair H. <ya...@01...>]

hi

in my driver i wish to clean a command after getting it.
so i need to call CleanCommand after GetCommand, then of course i need
to lock the two together so i will clean the correct command.
the code looks like this:

Lock();
GetCommand();
CleanCommand();
Unlock();

this of course is a DEAD LOCK. the access mutex is NON RECURSIVE.

solution is either a GetAndCleanCommand() method  which will Lock both
together , or declaring access mutex as recursive (which shouldn't have
any effect on written code).

any objections to this?
